Horizon battery and manufacturing method thereof

Abstract

The invention discloses a horizon battery and a manufacturing method thereof. Grid of existing horizon batteries is woven by glass fiber and lead composite. Lead layer on the surface of the grid is corroded fast, and conductivity is lowered when the lead layer is corroded. The horizon battery comprises a battery shell and an upper cover. A plurality of battery plate groups and partitions for blocking electrolyte circulation among the battery plate groups are disposed in the battery shell. Leading-out terminals connected to the battery plate groups are disposed at two ends of the battery shell. The battery plate groups comprise positive plates and negative plates which are alternately stacked, porous partition plates are disposed between the positive plates and the negative plates, and each positive plate and each negative plate comprise a plastic grid frame and a grid framework. The grid framework is made of lead alloy, and high in strength, corrosion resistance and conductivity. By the grid frame, usage of lead alloy is reduced, mass of the grid is lowered, and mass ratio energy of the horizon battery is improved.

Description

【Technical field】 [0001] The invention relates to a storage battery, in particular to a horizontal battery, belonging to the field of battery products. 【Background technique】 [0002] The pole plates of traditional lead-acid batteries are assembled vertically to the ground, and are also installed vertically to the ground when used. The lugs of the positive and negative plates are placed on the upper part of the battery, and the busbars and terminal posts of the conductive parts are connected from above. lead out. During the use of the battery, electrolyte stratification is prone to occur. During the discharge process of the battery, due to the high concentration of sulfuric acid in the lower part, the discharged capacity is relatively large. The sulfuric acid concentration in the upper part of the battery is low, and the discharged capacity is small. The upper part is charged first, and the active material has a tendency to gradually react and transform from the top to the ...

Problems solved by technology

[0004] However, since the plate grid of the horizontal battery is woven with glass fiber and lead composite material, although the lead material is saved, the grid will be damaged during use, especially during deep cycle use or storage. , the lead layer on the surface of the grid will corrode quickly, and the conductivity will be greatly weakened after corrosion, the capacity of the battery will be greatly reduced, and eventually the battery will fail.

[0005] At the same time, in the existing horizontal battery, the isolation between the monomers is filled with paraffin after the acidification is completed for isolation and sealing. Before the wax is filled, there is residual acid inside the battery, which is not good for sealing, and it is difficult to achieve good sealing and isolation. As a result, as long as the sealing and isolation are not good, there will be a string phenomenon, and the self-discharge of the battery will be large, which will easily cause the quality problem of poor consistency of the battery
